Kittle still posted a fine stat line on Sunday with 4 receptions for 44 scoreless yards and 1 carry for 9 yards, but his fantasy results were certainly disappointing against last season's easiest matchup for tight ends. Hopefully he'll make a full recovery during the week, but if Kittle can't go for Week 2, expect Jordan Reed to take a step up in the 49ers' injury-decimated receiver corps.
