DeShaun Watson threw for four touchdowns and 318 yards as the red-hot Houston Texans kept their playoff hopes alive with a 41-25 victory over the Detroit Lions on Thursday. Will Fuller finished with two touchdown catches and a total of 171 yards while defensive end JJ Watt returned an interception for a TD for the Texans, who have won three of their last four games. "We wanted to show we can have an explosive offence and defence," said Watson. "It was fun. "We are ready to get home to have some celebrations. We plan on feeding off this. We got Indy next week and we are ready to go." The game was one of two played on US Thanksgiving, one of the most important days on the American gridiron calendar. In the other game, the Dallas Cowboys host Washington at Dallas' AT&T Stadium. The NFL's showcase day was marred by the postponement of the marquee evening game between the undefeated Pittsburgh Steelers and the Baltimore Ravens after several Ravens players were diagnosed with the coronavirus this week resulting in an angry response from the Steelers' organization. The Ravens' outbreak now means that seven players are on the Covid-19 injury list, which indicates a player has tested positive or is considered a "high-risk" close contact with an infected person. Running backs Mark Ingram and J.K. Dobbins are among those on the list. The addition of defensive end Jihad Ward to the list on Thursday means that Sunday's game is also in jeopardy. Texans Tyrell Adams racked up a season-high 17 tackles and Duke Johnson rushed for 80 yards and also scored a touchdown in the win at Ford Field. Detroit's Matthew Stafford passed for 295 yards and one touchdown while Adrian Peterson gained 55 yards on 15 carries and scored twice for the Lions, who dropped to 4-7 on the season. Matt Prater's 29-yard field goal midway through the third quarter cut Houston's nine-point halftime lead to 23-17. Ka'imi Fairbairn's 26-yard field goal once again lifted the Texans' to a nine point lead. Watson's 40-yard touchdown pass to Fuller with just over 12 minutes remaining, plus Watson's short pass to Keke Coutee for the two-point conversion, made it 34-17. gph/bgs
