Weber (22) linked with the Waikato team yesterday and is likely to take some part in the next game for the Mooloos when they travel to Invercargill to take on Southland on Friday night.
Weber, a halfback, was not picked by Otago this season, losing out in the back-up role to Josh Renton.
He played for the New Zealand Colts in 2011, and was signed by the Hawkes Bay union straight out of Napier Boys' High School.
He played nine games for Otago last year, all as a substitute, as Japanese international Fumiaki Tanaka got the starts.
Weber, a University of Otago student, has been a star at sevens for the past couple of years, and produced standout appearances for Otago at the national tournament in Queenstown.
He has never been selected for the national sevens side, his small stature doing him no favours.
The Waikato side has made a disappointing start to its season, losing its past two games to Otago and Canterbury.
The team cannot call on the services of former All Black Brendon Leonard, who has left to play club rugby in Italy, while Tawera Kerr-Barlow is with the All Blacks and unlikely to be made available to play for his home province.
Waikato was forced to draft in a halfback from Australia, Michael Snowden, and is also using Kylem O'Donnell, who has returned from Taranaki.
Meanwhile, Weber's club team-mate, Gareth Evans, is the biggest injury concern for the Otago side for its match against Tasman on Friday in Nelson.
He twisted his ankle in the match against Hawkes Bay on Sunday and was walking gingerly yesterday.
Otago assistant coach Phil Young said Evans was the most in doubt for Friday night's match although plenty of other players had bumps and bruises.
He said the team was down on Sunday night after losing its first shield defence.
''But we have flushed that this morning and now we have to move on and get ready for Tasman,'' Young said.
The team has a short turnaround, having to play just five days after the Ranfurly Shield match.
Young was disappointed for the players, who had left nothing in the tank on Sunday, and it had been a hard loss to assimilate.
''Just the support we have had over the past nine days a lot of the guys thought they had let everyone down around the province,'' Young said.
Otago has a tough couple of games coming up, taking on Tasman in Nelson before facing up to defending Premiership champion Canterbury in Christchurch on September 14.
Its next game at home is against Manawatu on September 20.
