The Detroit Lions probably would prefer to hide rather than have their warts exposed to a national television audience on Thanksgiving Day.They could become even more unsightly if forced to use their third-string quarterback against the Chicago Bears at Detroit’s Ford Field.The Lions have lost four straight, and longtime starter Matthew Stafford looks set to miss his fourth consecutive game due to a back injury. His replacement, Jeff Driskel, is dealing with a hamstring injury.”He’s pretty sore still today,” coach Matt Patricia told reporters on Tuesday.If Driskel can’t play, the Lions will be down to David Blough. The 24-year-old out of Purdue never has thrown an NFL pass.”They’re a very competitive group, so they like to out-compete each other even with the preparation part of it,” Patricia said of his quarterbacks. “I think Blough falls right in line with those other two guys as far as the prep part of it.”Driskel has thrown four touchdown passes and four interceptions in his three starts. Three of those picks came against Washington last week, including one in the final minute that led to the Redskins’ game-winning field goal.Losing to Washington (2-9) has increased the heat on second-year coach Patricia, who has a 9-17-1 record after the Lions plucked him from Bill Belichick’s New England staff.”We’re fighting every single week to try to go out and do our best and make sure we’re putting ourselves in a position where we can have that opportunity to win,” Patricia said. “I also know that this is a process. I know there’s a lot in play here that we’re going through, and we’re trying to build, and we’re trying to do the best we can to improve and get better.”The Lions have lost their last two Thanksgiving Day games, including a 23-16 decision to the Bears last season.Chicago also won 20-13 when the two teams met in Chicago earlier this month. Driskel made his first start that afternoon and threw a touchdown pass to Kenny Golladay. The Bears’ Mitchell Trubisky threw three touchdown passes, however.
