Broncos OLT Ryan Clady partially tore the patellar tendon in one of his knees while playing basketball over the weekend and had to undergo surgery, according to reports.
It's believed that Clady will need three months to recover. The Denver Post reports that he is likely to miss the entire preseason and that the team is hopeful he will be ready to play by Week One of the regular season.
Clady started every game in his first two seasons in Denver and is already considered one of the best left tackles in the league.
