INDIANAPOLIS — It's time for the Week 4 version of the 2016 Colts Rookie Watch, where we take a look at stats and highlights to track the progress of each rookie on the Indianapolis Colts' roster.

So, without further ado, here we go:

• Austin Blythe, center: Blythe was active for the first time in his NFL career last Sunday against the San Diego Chargers, and even got four snaps with the offensive line, three of which coming in the third quarter, as he reported eligible along the line for three plays that culminated in a one-yard touchdown run by Robert Turbin.

Blythe also played a snap at left guard early in the fourth quarter, when starter Jack Mewhort temporarily went out with an injury.

The seventh-round selection out of Iowa also got five special teams snaps in the Colts' 26-22 victory.

• Le'Raven Clark, tackle: Clark, the Colts' third-round (82nd overall) pick in the 2016 NFL Draft, was active for the team's Week 1 matchup against the Detroit Lions, but was a healthy scratch for the team's next two games against the Denver Broncos and San Diego Chargers.

Clark — a Texas Tech product — played five snaps, all on special teams, during the Lions game.

• Matthias Farley, safety: Farley, an undrafted member of the secondary out of Notre Dame, was claimed by the Colts off waivers on Sept. 4 after he spent his entire offseason with the Arizona Cardinals.

After showing his abilities as a key replacement at safety for the first two weeks of the season, Farley was relegated back to a reserve role Sunday against the Chargers, logging 23 snaps, all on special teams.

Farley was active in both the Colts' first two regular season matchups, logging five snaps at free safety and 23 special teams snaps against the Lions, and playing a major role for the Indianapolis defense Week 2 against the Broncos, coming in as the team's nickel cornerback — having not ever playing at the position — after Darius Butler went down with a second-quarter hamstring injury.

In all, Farley played five snaps on defense and 23 snaps on special teams for the Colts in Denver, logging a tackle on defense and a special teams tackle in the game.

• Josh Ferguson, running back: Ferguson was signed by the Colts May 2 after he went undrafted following a decorated career at Illinois.

Seen as a threat both running and catching the ball out of the backfield, Ferguson has had a few opportunities to do both through the Colts' first three games of the season, as he has four rushing attempts for 3.5 yards and 10 receptions for 89 yards, with a long of 14 yards, accomplished on two occasions: Week 1 against the Lions and on Sunday against the Chargers.

In all, Ferguson played in 12 offensive and 11 special teams snaps against Detroit, and saw his playing time increase to 27 offensive and 14 special teams snaps against Denver.

He played 17 offensive snaps against San Diego, with 14 snaps on special teams. He had a key reception for nine yards for the Colts on their final, game-winning drive.

**

• T.J. Green, safety:** Green, the Colts' second-round (57th overall) pick this year out of Clemson, started the Week 1 matchup against the Lions.

He would collect three total tackles before suffering a sprained MCL, and he missed the Broncos game as a result.

Green returned for Sunday's game against the Chargers, however, playing a key role in the secondary with four total tackles in the team's victory.

In all, Green played in 47 percent (28 total) of the team's defensive snaps against San Diego.

• Joe Haeg, tackle: Haeg, the Colts' fifth round pick out of North Dakota State, got his first-career NFL start Week 3 against the Chargers, playing at right guard in place of an injured Denzelle Good.

He was on the field more than any other Colts player in the game, playing 76 total snaps — 71 on offense and five on special teams.

He missed the Week 1 game against the Lions with an ankle injury before making his NFL debut Week 2 against the Broncos.

In all, Haeg played in four special teams snaps against the Broncos, and remains one of the team's key backups at several spots along the offensive line.

• Ryan Kelly, center: Kelly was picked No. 18 overall by the Colts in the first round of the NFL Draft, and, as expected, he's been firmly entrenched as the team's starting center through the first three weeks of the season.

On Sunday against the Chargers, Kelly played all 71 snaps on offense, as well as logging a snap at special teams. He was a key piece up front to Frank Gore's 70 rushing yards and a touchdown in the first half, and was part of an offensive line unit that allowed just two sacks on the afternoon.

• Curt Maggitt, outside linebacker: Maggitt — one of the top pass rushers in college football before suffering a season-ending injury early in his senior year — was signed by the Colts as an undrafted free agent out of Tennessee on May 2.

He's played in all three of the Colts' regular season games thus far. On Sunday against the Chargers, he was credited with one assisted tackle on defense, while also making a stop inside the San Diego 20-yard line on a fourth quarter punt.

Maggitt played on three snaps defensively and 17 snaps on special teams against the Chargers.

Against Detroit, he was in on 20 total special teams snaps, while he got the first defensive snaps (27) of his career Week 2 against Denver, and also logged 20 special teams snaps in that game.

• Antonio Morrison, inside linebacker: The Colts took Morrison with one of their two fourth round (125th overall) picks in the NFL Draft after he proved to be a tackling machine at Florida.

He's played in all three of the Colts' regular season games, earning two tackles on defense and a team-best two special teams tackles Sunday against the San Diego Chargers.

In all, Morrison has played 26 defensive and 59 special teams snaps for Indianapolis.

• Hassan Ridgeway, defensive tackle: Indianapolis selected Ridgeway with its other fourth round (116th overall) pick in this year's NFL Draft out of Texas.

Ridgeway has appeared in all three of the Colts' regular season games so far, logging three total tackles for the defensive interior — including two stops Week 2 against the Broncos.

Ridgeway played in 27 defensive snaps Week 1 against the Lions and 21 defensive and five special teams snaps Week 2 against the Broncos. On Sunday against the Chargers, he logged 17 defensive snaps and in on one special teams play.

• Chester Rogers, wide receiver: Rogers, who went undrafted this year out of Grambling State, was able to earn a spot on the final 53-man roster with a strong preseason performance.

After being on the inactive list Week 1, Rogers made his NFL debut Week 2 against the Broncos, logging 23 snaps on offense and eight special teams snaps.

Rogers was targeted once against Denver, though he did not log a reception on the play.

He was targeted twice on Sunday against the Chargers, but did not come away with any catches once again. Early in the fourth quarter, it appeared Andrew Luck had connected with Rogers for a 58-yard reception down the sideline to the San Diego 1-yard line, but the wide receiver was called for offensive pass interference.

Rogers played in 31 total snaps (43 percent) on offense for the Colts against the Chargers.
