Beasley said Monday that he sustained a partially broken fibula in the Bills' Dec. 28 win over the New England Patriots. He was inactive for the team's regular-season finale against the Miami Dolphins on Jan. 3 and returned for the Bills' playoff run.
"I broke my fibula, but it's nothing that needs to be surgically repaired," Beasley told reporters. "It's not a full break. It was bad the first game I played. But after that you take a few meds and suck it up."
Beasley also appeared in the Bills' season-ending loss to the Kansas City Chiefs in Sunday's AFC Championship game.
"I knew the next [Dolphins] game was probably out of the question," Beasley said. "[The Bills] kind of told me it was [out of the question], so that one hurt a little bit.
"There was no way that I was going to miss the playoff game, especially after watching in Week 17. So I was going to figure it out, one way or the other."
Beasley, 31, had seven catches for 57 yards in the win over the Colts. He failed to make a catch against the Ravens. He had seven catches for 88 yards in Sunday's loss to the Chiefs.
The nine-year veteran had a career-high 82 catches for 967 yards and four scores in 15 regular-season games. Beasley also was named a second-team All-Pro. He is signed with the Bills through 2022.
"A lot of guys this year played hurt and didn't say anything, but when you've got a locker room that cares for each other and loves each other like this, that's kind of in the back of your head when you're on the field," Beasley said.
"You play for each other."
