Los Angeles Chargers

Brenen Thompson

WR

Thompson will miss a second consecutive game while working through a quadriceps injury. He was unable to practice during Week 4 prep, so a limited session ahead of Week 5 against the Broncos would indicate that the rookie fourth-rounder is progressing in his recovery. Marquez Valdes-Scantling and Derius Davis will both work in rotational roles behind Ladd McConkey (foot), Quentin Johnston and Tre' Harris in Thompson's absence.

Charlie Kolar

TE

Kolar fractured his forearm during the Chargers' Week 2 loss to the Raiders. He'll miss a second consecutive game due to his injury, but the positive news for the fifth-year tight end is that he ended Week 4 prep with a limited practice Friday. Head coach Jim Harbaugh told reporters after Friday's session that Kolar is "doing everything and anything possible" to return to the field, and he could get back as soon as Week 5 against the Broncos on Sunday, Oct. 11. For now, Oronde Gadsden will serve as the Chargers' TE1, with Hayden Rucci also in the mix for offensive snaps.

Donte Jackson

CB

Jackson entered the league's concussion protocol during the Chargers' Week 3 loss to the Bills. He progressively increased his practice participation this past week, culminating in a full session Friday, but Jackson will need to pass an evaluation by an independent neurologist in order to be cleared to play against Seattle.

Elijah Molden

CB

A hamstring injury prevented Molden from playing against the Bills in Week 3, but the sixth-year pro has drawn a questionable tag for Week 4 after logging three consecutive limited practices. One or both of Tony Jefferson and Genesis Smith could start at safety Sunday depending on the statuses of both Molden and Derwin James (hamstring).

Dalvin Tomlinson

DT

A hamstring injury will cause Tomlinson to miss two consecutive games. The next time he can play is Week 5 against the Broncos, though he would need to log at least a limited practice to have a realistic chance of playing against Denver. Rookie fifth-rounder Nick Barrett will continue to operate in a rotational role on the defensive line in Tomlinson's absence.
