San Francisco 49ers

In his first season in San Francisco, he started the first three games of the season before being placed on injured reserve.

On October 4, 2007 Jonas Jennings took a leave of absence from the San Francisco 49ers to deal with 'private matters'. He was replaced by Adam Snyder for the week 5 game against the Baltimore Ravens. It was announced the week after that he will rejoin the team as the starter at LT, but during the next game against the New York Giants he split time with his backup Adam Snyder.
Jennings sustained a high ankle sprain in the second quarter of the 49ers' loss to the Giants on October 21 and missed the subsequent two games. On November 5 he was placed on Injured Reserve; coach Mike Nolan stated that Jennings was to undergo surgery to remove "loose bodies" in his ankle, effectively ending his 2007-2008 season.
The 49ers brought Jennings back for the 2008 NFL season but did not guarantee him a starting position. During the 2008 season Jennings continued his injury-stricken career as a 49er when he injured his right shoulder. Although he insisted on remaining on the sideline as an emergency backup, ultimately he was placed on injured reserve to undergo his 3rd shoulder surgery.
Jennings was released by the 49ers on March 27, 2009.
