Reuben Foster is officially a member of the 49ers. The team announced on Friday that the linebacker has inked his rookie contract. 
The Niners kicked off their draft night by trading down from No. 2 to No. 3 and selecting Solomon Thomas. Later on, they traded back into the first round to select Foster. Foster appeared in 51 games (24 starts) during his four-year career at Alabama and registered 222 tackles, 24 tackles for loss, and eight sacks. In 2016, he was named First-Team All-America by the Associated Press and won the Butkus Award, the trophy given to the nation’s best linebacker.
Foster was believed to be a top ten candidate heading into draft week, but concerns about his character and injured shoulder hurt his stock. As he slid down the board, the Niners worked the phones hard to try and take the standout inside linebacker. At one point, the Niners were ready to trade into the middle of the first round for Foster, but they were able to get him several picks later and give up a lot less for the privilege. SF traded its No. 34 and No. 111 overall picks to Seattle to move up to No. 31 and nab Foster, who was reportedly the third-ranked player on its board.
With the signing, the 49ers now have eight of ten draft picks under contract. Thomas and C.J. Beathard are the only two unsigned rookies.
