Ex-Boro boys to face Glovers
Former Middlesborough duo Nicky Bailey and Scott McDonald are in line for their full debuts when Millwall host Sky Bet Championship new boys Yeovil.
Manager Steve Lomas has no fresh injury concerns as he begins his first full season in charge and the Northern Irishman could select up to six new signings.
Returning striker Steve Morison is likely to spearhead the Lions' attack while Richard Chaplow, Jermaine Easter and goalkeeper Stephen Bywater could all be considered.
Millwall last beat Yeovil at the Den in 2007 when second-half goals from Jamie O'Hara and Ali Fuseini cancelled out a James Walker strike.
Yeovil boss Gary Johnson could be without Jamie McAllister.
The 35-year-old defender is recovering from injury and is rated as doubtful for this clash, along with fellow defender Nathan Ralph.
Summer signings Alan Tate and Joe Jones are available to make their debuts at the back if the clash comes too soon for the injured duo.
Fellow new boys Michael Ngoo, Kieffer Moore and Sam Hoskins are vying for a place in Yeovil's attack, while midfielders Joel Grant and Billy Clifford will also be looking to make their first starts.
