The Indianapolis Colts suffered a huge loss before the season kicked off when star quarterback Andrew Luck announced his retirement.
Despite losing one of the best quarterbacks in the league, the Colts have done just fine on the field so far this season. Indianapolis opened the season with a loss to the Los Angeles Chargers.
However, the team has bounced back with victories over Tennessee and Atlanta to move to 2-1 on the season. The win over the Falcons came at a cost, though.
Star wide receiver T.Y. Hilton suffered a quad injury that forced him to leave the game.
Hilton racked up eight receptions for 65 yards an a touchdown during the game against Atlanta, but hasn't practiced since leaving the game.
On Friday afternoon, Hilton missed practice once again, putting his status for Sunday's game in doubt.
A four-time Pro Bowler, Hilton missed two games last year with various injuries but still finished the year with elite numbers.
Hilton leads the team in receiving this season and is easily the most-experienced wide receiver on the roster. If he can't go, the Colts will rely on Deon Cain and Parris Campbell to help carry the load.
Indianapolis and Oakland kick off at 1:00 p.m. ET on CBS.
