Durant entered the contest as the Falcons' leading tackler with 27, but his ability to pad that total is hindered due to an elbow ailment. If he fails to return Sunday, he'll emerge without making an impact in the box score.
Robenson Therezie will likely join the starting lineup alongside William Moore, who is back to his old ways as a stud IDP. Allen could be a decent option in his own right once he returns, after notching 17 tackles (15 solo) and an interception over the first three weeks of the season.
Falcons running back Tevin Coleman, who suffered a fractured rib in Week 2, is on track to return to practice this week, ESPN.com reports.
Coach Dan Quinn noted Monday that the Falcons are hopeful that Coleman could end up playing against Washington on Sunday, but such an outcome is not a lock at this stage
In Coleman's absence, fellow RB Devonta Freeman has gone on a tear, so even if Coleman is able to return to action in Week 5, he'd figure to be re-introduced to the team's backfield in a complementary role.
Falcons tight end Jacob Tamme (concussion) has been ruled out for Sunday's game against the Texans, D. Orlando Ledbetter of the Atlanta Journal-Constitution reports.
Levine Toilolo will likely step in as the primary tight end in an offense that mostly ignores the position. Tamme has eight catches and 11 targets in three games, after Toilolo caught just 31 passes on 54 targets as a 16-game starter last year.
Rams linebacker Alec Ogletree underwent surgery Tuesday on a fractured fibula and will be miss at least eight weeks, Jim Thomas of the St. Louis Post-Dispatch reports.
What was initially termed an ankle injury has been confirmed as a broken leg, threatening the remainder of Ogletree's season. He was easily on pace to achieve a third 100-tackle campaign in a row to kick off his career. However, his absence will make way for Akeem Ayers to serve as the Rams' weak-side linebacker.
