George Kittle was left flabbergasted with a "diabolical" play that his quarterback, Brock Purdy, made during their 37-24 victory over the Tennessee Titans on Sunday.In the post-game press conference, the six-time Pro Bowler praised the quarterback for taking the risk and running the ball down the field while juking his opponents. However, Kittle also showed concern for Brock Purdy, stating that he should take care of his physical health and not injure himself on the field."He's Jesus Christ Lizard, running on water," Kittle said. "Just, no ball security, fake pitching at the end of a 40-yard run. Absolutely just diabolical behavior by our QB1, but I love it."As long as he's running out of bounds, I don't care. Just don't take a hit. I just don't need that in my life."George Kittle was referring to a play that Brock Purdy made in the third quarter of the game. During a first-and-10 play, the 49ers quarterback decided to run the ball after the snap and escape from the pocket.Purdy weaved his way through the Titans' defense while pump-faking a defender. The quarterback also fake-pitched Titans linebacker Cody Barton before running to the sidelines.Purdy ended the game completing 23 of 30 passes for 295 yards and three touchdowns. On the other hand, Titans quarterback Cam Ward completed 18 of 29 passes for 170 yards and two touchdowns.The $265 million quarterback has had a roller coaster of a season so far with the 49ers. Purdy injured his left toe and shoulder during their season opener against the Seahawks, resulting in Mac Jones taking over. He then aggravated the injury in Week 4 and was sidelined until making his return last month during their 41-22 victory over the Cardinals.The 49ers are placed third in the NFC West with a 10-4 record and a four-game winning streak.Brock Purdy shares his honest thoughts on the 49ers after Week 15 victory over the TitansAfter the game, Brock Purdy joined FOX Sports for a sideline interview on the field.When asked to talk about the team's offensive performance, the quarterback did not hesitate in heaping praise on his teammates. He also shared his honest thoughts about overcoming adversity and injuries to put up a 10-win campaign with the 49ers."I feel like everybody just did their job," Purdy said. "When defense got stops, we capitalize and go out and score. The mentality to just keep going, never get complacent. The O-line did great, run game was great. ... It was a great team win."Resilience. It's the NFL, guys go down, guys step up. Everyone's done a great job across the board. With every position group the next guy is stepping up, doing their job and doing what it takes to win. That's what it looks like when you have a great team and we got a great team. We just got to take it one game at a time."The 49ers will next face the Colts on Monday, Dec. 22, at 8:20 p.m. ET.
