Pierce will likely be limited for some or all of training camp by his ankle injury, Stephen Holder of ESPN.com reports.
Pierce underwent surgery in late March to address an ankle injury, and his recovery period is expected to linger into training camp. He still has time to heal up before the Colts kick off regular-season play Sept. 13 against the Ravens, but Pierce's recovery progress will be worth tracking throughout training camp. Josh Downs is likely to function as the Colts' top wide receiver in practice if Pierce sits out, with Ashton Dulin, Nick Westbrook-Ikhine and rookie seventh-round pick Deion Burks among the players jostling for playing time in Indianapolis' wide receiver room.
