ANDERSON, Ind. – Henry Anderson will be an observer when the Colts begin Training Camp practices on Wednesday afternoon.

The Colts placed Anderson on the physically unable to perform list on Tuesday.

Even though Anderson (knee) is on PUP, he can come off the list at any time during Training Camp. In the regular season, players on PUP must miss the first six weeks.

Jim Irsay said in June that Anderson, who tore his ACL last November, might not be ready to go for Week One of the regular season.

The real surprise on Tuesday came from safety Clayton Geathers going on the non-football injury list.

Geathers will miss the start of Training Camp, but can come off the list at any time. Tuesday's designation indicates Geathers suffered that injury away from the team complex. Geathers was the starting safety throughout the team's offseason program.

If Geathers, the expected safety starter next to Mike Adams, has to miss significant time, that should mean a much more expanded role for second-round pick T.J. Green.

Chuck Pagano will update Geathers' status on Wednesday morning, at the head coach's first media session of camp.

Also on Tuesday, the Colts placed undrafted tight end Darion Griswold on the physically unable to perform list and fellow undrafted tight end Mike Miller on the non-football injury list.

Without Griswold and Miller, the Colts are left with five healthy tight ends on the 90-man roster (Dwayne Allen, Jack Doyle, Mo Alie-Cox, Chase Coffman and Emil Igwenagu, who the team signed last week).

Later on Tuesday, the Colts added veteran tight end Coffman, placed running back Tyler Varga on the Reserve/Did Not Report list and waived cornerback Daniel Davie.
