The Buffalo Bills announced Tuesday that they placed wide receiver Marcus Easley on season-ending injured reserve.
The Buffalo News reported that Easley has been diagnosed with a heart ailment, but there were no further specifics. The receiver left practice early Friday and didn't make the trip to Kansas City for the team's opening game on Sunday.
The Bills official website said Easley was seen pointing to his chest when talking to athletic trainers at Friday's practice.
The team also signed cornerback Terrence Wheatley to their practice squad. The 5-foot-9, 185-pound Colorado product was a second-round draft pick of the New England Patriots in 2008.
