Elijah Mitchell
Mitchell (knee) isn't practicing Wednesday, Matt Maiocco of NBC Sports Bay Area reports.
Analysis: Mitchell barely played the first two weeks of the season and then suffered a knee injury when he got 13 touches in a 30-13 win over the Giants in Week 3. He missed the Week 4 win over Arizona and now appears in danger of missing Week 5 against Dallas, though a report earlier this week suggested the Niners consider him day-to-day. In any case, Christian McCaffrey doesn't figure to come off the field much Sunday night in a battle between NFC heavyweights.
Dre Greenlaw
Greenlaw (ankle) was a non-participant at the 49ers' practice Wednesday, Eric Branch of the San Francisco Chronicle reports.
Analysis: Greenlaw has been dealing with an ankle issue the last couple weeks, but considering he was able to play in Sunday's 35-16 win over the Cardinals, the linebacker seems likely to be available for the team's Week 5 matchup with Dallas. The 26-year-old will have two more practices this week to increase his participation.
DeeBo Samuel
(ribs, knee) will play at "less than 100 percent" when the 49ers face the Cowboys on Sunday night.
Analysis: Samuel was nearly absent in Week 4, failing to log a target. Even if he gets more involved this coming Sunday, he'll be playing at less than full strength. This isn't great news for a receiver whose production has already been limited by the stellar play of Christian McCaffrey and Brandon Aiyuk.
