Raiders quarterback Aidan O'Connell reportedly broke his thumb in the game against the Rams

Las Vegas Raiders quarterback Aidan O'Connell is believed to have suffered a broken thumb in Sunday's game against the Los Angeles Rams, according to preliminary tests, NFL Network Insider Ian Rapoport reported, according to sources.

O'Connell, the second-year signal-caller who just reassumed the starting job a week ago, will undergo another evaluation on Monday to determine the extent of the injury, Rapoport added.

O'Connell left the game after two drives in the first quarter and was replaced by Gardner Minshew. A return is currently questionable. O'Connell completed 6 of 10 passes for 52 yards in his two possessions against Los Angeles, leaving the game tied 0-0.

This season, O'Connell went 46 of 72 for 403 yards, two touchdowns and two interceptions on Sunday. However, Las Vegas lost its first start to the Steelers 32-13 in Week 6.

O'Connell's injury is the latest development for a Raiders team in transition. After benching Minshew for AOC in Week 6, Las Vegas traded Davante Adams to the New York Jets on Tuesday, sending its most talented offensive player out of town while the rest of the 2-4 team struggles to make the playoffs -To remain competitive.
