Wolverhampton legend Mikael Max makes his return to Monmore Green tonight - riding for the opposition.
Max, who suffered a badly broken thigh last summer, was not considered for Wolves' team plans over the winter due to the severity of the injury, and he signed a contract to ride for Arena-Essex once he had regained fitness.
The Swede has gradually been regaining his speed with the Hammers, proving that he has not lost any of his ability from the starts, and clearly he will relish facing the likes of brother Peter Karlsson and Wolves' other top gun Billy Hamill tonight.
Karlsson and Hamill both rode to reasonably straightforward maximums last week against Oxford, a team desperately short on top-end strength, but it may be a different story tonight with Max backed up by in-form Finn Joonas Kylmakorpi, another rider with a fine record at Monmore.
2005 Wolves skipper Steve Johnston will no doubt be keen to prove a point after a disappointing season last year which left him the subject of terrace criticism and not under consideration for a return this season.
Karlsson said: "Arena haven't surprised me because with riders like Kylmakorpi, and Paul Hurry at reserve, you are always going to get points.
"They will make it hard for us, but we have to keep our home run going. I'm sure Mikael will be keen to win some races though, and it is good to see him back on track."
Wolves' options at reserve, meanwhile, have been reduced by an injury to William Lawson. who cracked a bone in his elbow at Glasgow last Monday. Initially it was thought that the young Scot had escaped unscathed, but a hospital visit in the middle of last week revealed the break.
However, the full extent of the damage cannot be confirmed until the fluid on the elbow has subsided and both Wolves and Edinburgh, Lawson's Premier League club, hope that he will be able to return to hospital early this week to gain an accurate prognosis.
That puts more pressure on Christian Hefenbrock to keep up his rapidly improving form, especially tonight with Lawson's doubling-up colleague, Ben Wilson, also unavailable due to the World junior team cup in Germany.
Wolves travel back to Pur-fleet on Wednesday, although this is will be an Elite League 'B' fixture as they have already raced once at Arena this season. The Midland side were narrowly beaten first time around, and they urgently need to notch that first away win if they are to mount a challenge to the top four.
Coventry have most of the week off after a chaotic spell including a turbulent meeting at Arena last Wednesday when they felt robbed of a win by controversial referee Frank Ebdon, who excluded both Bees riders in the last race.
The reigning champions take on Belle Vue, the team who they beat to lift the crown, in a potential thriller at Brandon on Friday.
