The Vikings on Saturday announced they have acquired cornerback Tramaine Brock from the Seahawks via trade.

Originally signed by San Francisco as an undrafted free agent in 2010, Brock has spent the past seven seasons with the 49ers but was released in April 2017. Brock was signed by Seattle on Aug. 16.

Brock started 40 of the 80 games he played with San Francisco and has 11 career interceptions. In 2016, he started all 16 games and recorded 58 tackles (48 solo), one interception and a forced fumble.

Here are five things to know about Brock:

1. College connection

Brock spent time at three different colleges prior to his pro career. The cornerback first played at Mississippi Gulf Coast, which is regarded as one of the nation's top junior college programs. As a sophomore, he helped the Bulldogs achieve a perfect 12-0 record. Brock played a total of 17 games for the Bulldogs and totaled 72 tackles, seven interceptions and two forced fumbles.

Brock is not new to Minnesota. As a junior, he played for the Golden Gophers and recorded 73 tackles, six passes defensed, one interception, three forced fumbles and a fumble recovery.

He then returned to Mississippi to play for Belhaven College as a senior. There, he played 11 games and recorded 51 tackles, 13.5 tackles for loss, 2.5 sacks, six interceptions, 10 passes defensed and one fumble recovery. He also was utilized on special teams and returned 29 kicks for 505 yards.

2. Starting out in San Francisco

Brock is not the first to come to Minnesota after starting his career with the 49ers. Vikings long snapper Kevin McDermott was originally signed as an undrafted free agent and spent the 2013 season on San Francisco's roster with Brock. The cornerback also overlapped with Vikings offensive lineman Nick Easton on the West Coast.

3. Made in Mississippi

A Mississippi native, Brock joins defensive tackle Tom Johnson in calling the southern state home.

Brock's hometown of Gulfport is located less than an hour from Moss Point, Mississippi, where Johnson was born and raised.

4. Clutch play

Brock made highlight reels for his game-saving play against the Falcons in 2013.

The Week 16 game was a rematch of the previous year's NFC Championship game, and Atlanta's Tony Gonzalez scored a touchdown to decrease its deficit and make it a 27-24 game with just over two minutes remaining. The Falcons recovered the subsequent onside kick and within two plays were at the 49ers 10 and threatening to score.

On the next play, however, Brock deflected a Ryan pass. The ball was intercepted by San Francisco's NaVorro Bowman, who returned it 89 yards for a touchdown to seal the game.

The Falcons did make a final effort to score another touchdown, but Brock intercepted Ryan's pass in the end zone as time expired.

5. Success story

Brock's journey from undrafted rookie to starting cornerback may be atypical, but it's a storyline the Vikings are familiar with. A number of undrafted players have gone on to make careers for themselves in Minnesota, including starting receiver Adam Thielen and cornerback Marcus Sherels, who has been a standout punt returner for his hometown team. Brock and Sherels both played for the Gophers during the 2008 season.
