Danieal Manning's return yards prospects

As an owner in a return yards league (10 yards per point), I've come to rely on Danieal Manning for high performance at DB. Unfortunately, the Vikings weren't the only ones who got burned in Week 10 by the use of Devin Hester for KR duties. Should I be worried about Manning's return yard prospects going forward, and more immediately, should I start him in Week 11 vs. Miami?

We play two DBs and my other choices on the roster are Yeremiah Bell vs. CHI and Tramon Williams at MIN. League scoring is 1 pt per tackle, 3 points per sack/INT/FFUM. Many thanks!

I'd be starting Bell and Williams over Manning anyway so that kind of answers your question .
