One quarterback in, one out. That’s been the story for Teddy Bridgewater and Sam Bradford over the last season. Bridgewater suffered a terrible injury just before the start of the 2016 season, and the team moved him to injured reserve for the year. Bradford was acquired in a trade with Philadelphia, and was starting for the Vikings by week 2 of the season. This season, Bridgewater started the season on the PUP list, while Bradford had a career game to open the season against the New Orleans Saints. Bradford suffered what appeared to be a mild knee injury in the game, so Case Keenum got the start the following week. Bradford didn’t see the field again until the game against the Chicago Bears, where it became quickly apparent that his knee hadn’t fully recovered and he was mercifully benched for the second half, allowing Keenum to get the Vikings back into position to win the game and has been the starter since then.
Bridgewater was eligible to practice with the team after the sixth game of the season, and the team had a three week window to decide whether to put him back on the 53-man roster, or shut him down for the remainder of the year by moving him back onto injured reserve. Today was the final day for the Vikings to make that decision. In the meantime, Sam Bradford got arthroscopic surgery on his ailing knee yesterday and was looking at a minimum six-week recovery time, so it makes sense for the team to put him on the injured reserve list, where he could be brought back onto the roster if the Vikings make the playoffs (teams can bring up to two players back from IR after a minimum of eight weeks).
Teddy Bridgewater, according to all the media reports, has been looking good in practice and his team-mates have been quite enthusiastic to get him back, but he hasn’t played any football since August 2016 and it’s probably unreasonable to expect him to pick up where he left off at that point without at least a few weeks of re-familiarization and actual game reps. If he has no set-backs and looks comfortable on the field, he could take over for Keenum in a few weeks, or it might take longer and Keenum will be the starter for much of the second half of the season. Nobody knows until Bridgewater gets onto the field.
