Zimmer: Vikings 'doing everything' to get Bradford ready for Sunday

Minnesota Vikings quarterback Sam Bradford will miss yet another day of practice Wednesday, but the team remains optimistic about his chances of returning to the field in Week 4.

"We're doing everything (we) can," said head coach Mike Zimmer, according to Chris Tomasson of the St. Paul Pioneer Press.

Bradford hasn't been able to play since his outstanding performance in the Vikings' season opener, when he completed 84.4 percent of his passes and threw for 346 yards and three touchdowns.

Backup Case Keenum looked much better in his second start of the season, throwing for 369 yards and three scores against the Tampa Bay Buccaneers.

The Vikings play host to the Detroit Lions in Week 4. The unclear quarterback situation is keeping their game line off the board, according to Covers.com.
