Nothing like a shot of healthy nepotism to inspire a potential promotion challenge and Coventry were delighted to learn yesterday that Mike Umaga, their new head coach, has persuaded his brother Tana, the New Zealand captain, to make an appearance at the Butts Stadium next season.

The All Blacks are touring Europe in the autumn and not only will Tana Umaga be putting in a few sessions with his elder brother but the entire New Zealand squad will use the Butts as their English base.

Club chairman Keith Fairbrother said: "We've got some big signings in mind, we've doubled our attendances and we'll really be thinking about promotion next September. We're still on the world stage."

And there is much to occupy Coventry's thoughts during the last weeks of this season, not least the decision they made yesterday to cite Otley's Tongan wing, Waisale Sovatabua, for an alleged attack on Coventry centre Nik Witkowski last Saturday.

Already incensed by the fact that they lost the match to a penalty try awarded for an offence of handling in the ruck when play, they claim, was 27 metres from their line, they have studied film of the Sovatabua incident.

They are adamant that the Tongan stamped on the Canadian's head.

Coventry's chief executive, Ian Carvell, said: "We've had a good look at the video and we're are satisfied that it was a deliberate stamping. There are serious cuts around our player's eye; this could have blinded him, so we have started the citing procedures."

Much else is happening at Coventry. They have signed Orrell wing, James Moore, for next season and have pounced on the 21-year-old Reading flanker, Tom Johnson, who is said to be the outstanding back-row man in the Third Division (South).

In addition, they are engaged in negotiations with two Premiership players plus a Welsh centre from the Celtic League.

As Steve Williams, their forwards coach, has returned to Northampton, Coventry are talking to a Premiership lock as a possible replacement.

They are being careful not to mention any names at this stage and in that context are not at all amused by the antics of one player agent who announced rather indiscreetly that Coventry's scrum-half, Shaun Perry, was about to join a Premiership club, Gloucester, or one about to be, Bristol.

"That," Carvell said, "has caused a lot of embarrassment."

He added, though, that if Perry was elevated "...he will have gone from Dudley Kingswinford to the Premiership in two years. That's a big achievement on his part and on Coventry's. We wish him well."

On top of all that frantic activity, Coventry will face one-time promotion favourites, Exeter, at the Butts on Saturday. Fairbrother said: "We intend to destroy their last remaining hopes of promotion."

Recent unfavourable results have been influenced by the absence of Paul Jones and Pila Fipita from the backs and Dan Farini from the back row.

All three could be back in action this week.
