The San Francisco 49ers are looking for reinforcements for their defensive line.

In the week of their first preseason game, they lost defensive end Drake Jackson for the year and defensive tackle Kalia Davis for at least half the season. According to Aaron Wilson of KPRC 2 in Houston, they are now practicing with a trio of defensive linemen.

Abdullah Anderson, Marquise Copeland and Nicholas Williams practiced for the 49ers on Tuesday on the team’s day off.

Anderson, 28, has been on five teams in five seasons. He entered the league with the Bears before moving on to the Vikings, Packers, Falcons and Commanders. Anderson has eight starts in 33 NFL games with 54 tackles, four tackles for loss and 2.5 sacks.

Copeland is a four-year NFL veteran who debuted as an undrafted rookie with the Los Angeles Rams in 2020, the year 49ers assistant head coach Brandon Staley was the defensive coordinator in LA. Copeland made nine starts in 26 games in his four years with the Rams. His most productive season was 2022, when he made all nine of his starts. That year, he had 31 tackles, two tackles for loss, and 1.0 sacks.

At 34, Williams is the oldest and most experienced player on the team. He has been in the NFL since 2014 and has played 97 games with 48 starts for the Chiefs, Dolphins, Bears, Lions, Giants and Chargers. He was with the Chargers last year when Staley was head coach. In 14 games (six starts), he recorded one sack and seven tackles for loss.

All three play on the interior, where the 49ers are particularly thin at the moment. It wouldn’t be a surprise if they chose a player like Copeland, but his stature suggests he could also play a little further out, where San Francisco may need help.
