DAVIE, Fla. -- The Miami Dolphins (5-8) are expected to be without two defensive starters in Sunday's game against the San Diego Chargers (3-10). Starting outside linebacker Jelani Jenkins (ankle), who led the team in tackles last season, and defensive tackle Earl Mitchell (calf) are listed as “doubtful” and “out,” respectively.

Miami will rely on a pair of rookies to start against San Diego. Undrafted linebacker Neville Hewitt will get his second start and second-round pick Jordan Phillips will start his second game for Mitchell, according to head coach Dan Campbell.

Dolphins second-leading receiver Rishard Matthews (ribs, chest) is listed as “questionable,” but Campbell said he’s not optimistic. Starting cornerback Bobby McCain (concussion) also is listed as questionable but is expected to return. He had full participation in practice on Friday.

“Bobby McCain will go through the last series of (concussion) protocols today,” Campbell said. “We expect him to be cleared.”

Here is the full injury report for Miami:

Out: RT Ja'Wuan James (toe), DT Earl Mitchell (calf)

Doubtful: LB Jelani Jenkins (ankle)

Questionable: WR Rishard Matthews (ribs, chest), CB Bobby McCain (concussion)

Probable: WR Jarvis Landry (knee), RB Lamar Miller (ankle), G Billy Turner (calf), RB Damien Williams (back)
