1:22Vikings head coach Mike Zimmer remained coy about Sunday's quarterback situation, not naming Case Keenum the starter.
Keenum was listed as "limited" in practice Wednesday because of a chest issue. Keenum is 3-2 as a starter and has led the Vikings to four victories, including the second half in Chicago, while Bradford continues to be missing from practices with lingering issues in his left knee.
"I don't know," Zimmer said of his starting quarterback. "We'll see."
Teddy Bridgewater practiced Wednesday and is expected to make the trip to London. When asked about Bridgewater's status, Zimmer said, "I think I know what I'm doing, but it's the medical clearance at the end of the day."
However, Bridgewater will need to be activated from the physically-unable-to-perform list before he can play. The Vikings still have another 1½ weeks before needing to make that decision.
The Vikings left for London in Wednesday and will hold their first London practice on Thursday evening.
