Cook to play with brace Week 4?

Pro Football Talk hears that the "current expectation" is for Vikings RB Dalvin Cook to wear a brace on his injured left shoulder and play vs. the Saints in London next week. We wouldn't go locking Cook into Week 4 fantasy lineups just yet but will track Cook's status throughout this coming week. RB Alexander Mattison should be owned in all fantasy leagues in case Cook misses further time.
