Richardson missed practice on Thursday, which marked his second missed practice in a row, as noted by Josh Alper of ProFootballTalk.com. Even though he's missing practice, he's still expected to suit up in Week 10 when the Colts host the St. Louis Rams, as Stephen Holder of the Indianapolis Star reported:
Brown has recently been getting more heavily involved in Indianapolis' offensive game plans, even before Richardson's ankle injury cropped up this week. He's received 20 touches in the past two games, during which time Richardson touched the ball 38 times.
The veteran out of Connecticut has been effective when given an opportunity to play, too.
For the season, Brown has totaled 244 yards rushing with one touchdown, averaging 6.3 yards per carry, while catching nine passes for 75 yards.
His yards-per-carry average is more than double the production the Colts have gotten out of Richardson this year, as he's managed just 2.99 yards per carry since joining the team in late-September while scoring just two touchdowns.
Brown's recent increase in production signals the Colts have begrudgingly accepted the fact Richardson isn't as explosive as the team had hoped when it traded away next year's first-round draft pick to land him.
Given the current situation—Richardson is banged up with an ankle injury and Brown has provided excellent production—the Colts should continue to get Brown more involved in the game plan.
He's an excellent receiver out of the backfield who has caught 18 of 25 passes thrown his way the past two seasons, and he displays good vision when running between the tackles.
If Richardson's injured ankle keeps him out of action, the Colts won't hesitate to give Brown a full workload. Even if Richardson suits up and starts this weekend, Brown will be called on often.
The Rams feature one of the NFL's worst fantasy defenses against opposing running backs, which boosts Brown's fantasy stock even more. St. Louis allows 20.9 points per game to opposing running backs in ESPN standard-scoring leagues, which is the fourth-worst mark in the NFL.
Start Brown if you've got him.
After Week 10, the Colts face the Tennessee Titans twice in the next three weeks. The Titans give up 19 points per game to running backs, which ranks eighth worst in the NFL.
If you're a fantasy owner looking for a decent flex option, now's the time to see if he's still available on the waiver wire—and then start him if you land him.
