Indianapolis Colts tight end Coby Fleener sat out Tuesday's practice with a concussionm per WISH Channel 8.

Fleener's injury, coupled with the foot injury that has already taken down Dwayne Allen, leaves the Colts with just two healthy tight ends for now - Justice Cunningham and Dominique Jones.

The Colts are likely to add a tight end in the coming days to help them get through camp until Fleener is cleared to return.
