England batsman Eoin Morgan's participation in Tuesday's second Twenty20 International against New Zealand remains in the balance, after he "jarred" his back during the series opener late last week.

Morgan did not take part in Monday's practice session and is yet to have a scan or injection, as the injury is thought to be muscular. His absence would spell a return to the XI for young Joe Root, who impressed on debut against India recently.

Batsman Jonny Bairstow and seamer Jade Dernbach, meanwhile, have been cleared to play at Seddon Park in Hamilton after recovering from minor finger and arm injuries respectively.

New Zealand have been availed the services of all-rounder Grant Elliott and fast bowler Ian Butler again.

Elliott and Butler did not play in the first T20I, which England won by 40 runs to take a one-nil lead in the three-match affair, due to respective quadricep and ankle injuries. All-rounder Jimmy Neesham, who had been called up as a replacement, has subsequently been released from the squad.
