With wide receiver Darrius Heyward-Bey out for an undisclosed period of time with a knee sprain - suffered during practice on Sunday - the Colts are most likely looking for "a warm camp body" to run routes during the receiver drills while DHB heals up.
DHB was seen with a knee brace on during Monday morning's walk through.
Thus, the Colts parted ways with linebacker Monte Simmons today in an apparent precursor to them signing a wide receiver. Simmons is a third-year veteran who went undrafted out of Kent State. In 2011, he was on the 49ers roster. In 2012, he was with the Philadelphia Eagles.
Colts offensive coordinator Pep Hamilton told the media on Monday that the teams has capable back-up wide receivers who can step up and perform. It's assumed that one of these back-ups is T.Y. Hilton, a player who could take Heyward-Bey's job as the starting outside receiver if he continues to build off of the impressive camp he's had so far.
