San Francisco 49ers receiver Mike Evans remains week-to-week with Achilles tendinitis, leaving his availability uncertain for Sunday’s game against the Dallas Cowboys.

Evans has missed the past two games and has not practiced this week. He has not practiced since leaving midway through San Francisco’s 23-17 win over the Washington Commanders on Oct. 19. The 49ers are 7-1 entering the Dallas game.

Evans, 33, is in his first season with San Francisco. Fellow receiver Deebo Samuel, who has been out since Week 5 with a hamstring injury, returned to practice on a limited basis Wednesday. General manager John Lynch said last Thursday that the team hoped to get both receivers back in the coming weeks.

Coach Kyle Shanahan said on KNBR on Thursday that the 49ers are trying to bring Evans back carefully rather than risk losing him again immediately.

“But what we’re trying not to do is have him come back and then be out right away. We’re trying to build him up the right way, so hopefully, it can last a little bit,” Shanahan said.

Shanahan said the team assesses Evans at the beginning of each week and that he was closer to returning this week than last week.
