Overview

• San Francisco 49ers quarterback Joshua Dobbs will start in place of Brock Purdy, sidelined with an elbow injury, for the Week 18 game against the Arizona Cardinals.
• Dobbs, a free agent in March, views the game as an opportunity to showcase his abilities for potential suitors after spending most of the season as the 49ers' third-string quarterback.
• The Cardinals, also dealing with injuries, will rely on running back Michael Carter and DeeJay Dallas following the placement of James Conner and Trey Benson on injured reserve.
• Both teams are out of playoff contention, with the 49ers holding a 6-10 record and the Cardinals at 7-9 after losing five of their last six games.
• Key players for both teams, including George Kittle, Deebo Samuel, and Nick Bosa for the 49ers, and Kyler Murray for the Cardinals, are either limited or unavailable due to injuries.
