The Minnesota Vikings, after losing starting quarterback Teddy Bridgewater for the 2016 season with a severe left knee injury, acquired Sam Bradford in a trade with the Philadelphia Eagles on Saturday.

In return, the Eagles will receive the Vikings' first-round draft pick in 2017 as well as a conditional fourth-rounder in 2018.

The Vikings had inquired about Bradford after Bridgewater's injury earlier this week, sources told ESPN's Adam Caplan, but the Eagles were said to be happy with Bradford's progress this preseason.

With Bradford's exit, Chase Daniel will likely begin the regular season as the starting quarterback for Doug Pederson and the Eagles, with rookie Carson Wentz waiting in the wings. The No. 2 overall pick in this year's draft, Wentz missed the final three preseason games after breaking his ribs.

Bradford re-signed with the Eagles in March to a two-year, $35 million deal with $22 million fully guaranteed.

The Eagles paid Bradford's $11 million signing bonus, a source told Caplan, but the Vikings are responsible for the rest of his contract -- $20 million in base salaries and a $4 million March 2017 roster bonus.

Bradford will now play for his sixth offensive coordinator -- Norv Turner -- in seven seasons. Vikings tight ends coach Pat Shurmur was Bradford's offensive coordinator with the Eagles last season and for two seasons (2009-10) with the Rams.

Bradford, the first-overall selection in the 2010 draft out of Oklahoma, has thrown for 14,790 yards, 78 touchdowns, 52 interceptions in his 63 career games -- all of which are starts.

He will be reunited with former Sooners teammate Adrian Peterson, who was told of the trade before Saturday's Oklahoma-Houston game.

"I'm pumped," Peterson said.

The Vikings have four quarterbacks on their roster, but undrafted rookie Joel Stave suffered an injury during the team's fourth preseason game and Brad Sorensen has been told he will be waived before Saturday's roster deadline for teams to reach 53 players, a league source told ESPN.

Journeyman quarterback Shaun Hill had taken over as the starter after Bridgewater was placed on injured reserve Wednesday. The Vikings also have second-year signal-caller Taylor Heinicke on the roster; he is coming back from a pre-training camp injury, which landed him on the active/non-football injury list.

Heinicke's injured left foot should be fully recovered in three weeks. League sources told ESPN the team was expecting Heinicke to challenge Hill for the No. 2 job in training camp had he not suffered his injury.

Why did they just give away a 1st rd pick and a conditional 4th for a player that's probably getting injured?

Probably because they think they can compete with the team that they have and wanted a legit starter?

I also here that Bridgewater's injury was very bad.

Man, they're just gonna throw their picks in the trash when he gets injured.

I think teams can afford to take risks on trading picks if they already have a roster that is well built anyways.

You can never have enough talent.

That is true
