Southampton loanee Hoskins netted after just 20 seconds at Glanford Park, but the Millers, despite dominating large parts of the game, had to settle for a share of the spoils as Andrew Wright's equaliser levelled matters for the Iron.
18 year-old trialist Adam Hurrell partnered Hoskins and Alec Denton in a youthful attack. Hurrell is with the club from Swansea City for an initial week.
Starting 11: Warrington, Tonge, Royles, Cresswell, McKay, Newey, Woods, Warne, Hurrell, Denton, Hoskins.
