Lam brings in Muliaina
The men from the West can load the pressure onto Scarlets and Edinburgh by taking the scalp of Cardiff at The Arms Park tonight (KO 7.35, TG4).
The experience of Mils Muliaina will be important at the back as they look to keep Gareth Anscombe and Alex Cuthbert in check.
Connacht have lost nine of their last ten against The Blues where the artificial pitch can be a distinct advantage.
They have been boosted by the announcement yesterday of wing-cum-centre Danie Poolman to extend his contract out by two years to the summer of 2017.
Cardiff: R Patchell; A Cuthbert, C Allen, G Evans, J Tuculet; G Anscombe, L Williams; S Hobbs, K Dacey, T Filise, J Hoeta, L Reed, J Turnbull, E Jenkins, J Navidi.
Connacht: M Muliaina; T O'Halloran, D Poolman, D McSharry, M Healy; C Ronaldson, J Cooney; D Buckley, T McCartney, R Ah You, M Kearney, A Muldowney, J Muldoon (capt), J Heenan, G Naoupu.
