New England Patriots quarterback Tom Brady‘s ankle injury is “significant,” CSN New England’s Tom Curran reported Sunday, citing two sources familiar with Brady’s injury.

Brady played through the injury on Sunday, leading the Patriots to a 37-22 victory over their AFC East division rival, the Buffalo Bills. Brady had his best game of the season, completing 27 of 37 passes for 361 yards and four touchdowns.

According to Curran, the 37-year-old Brady “needed a lot of therapy” to play in Sunday’s game. According to the report, Brady rolled his ankle in practice on Friday, which led him to be listed as “questionable” ahead of Sunday’s contest.

Earlier this month, there were reports that personnel and coaching changes have led to tension between Brady and the Patriots’ coaching staff. The rift, according to the reports, could reportedly lead to him finishing his career with another team.
