Northampton Saints forwards Teimana Harrison and Jonathan Fisher have both signed new contracts with the Aviva Premiership champions.
Academy product Harrison, 22, has made a total of 22 appearances for the team.
Meanwhile, 26-year-old Fisher has played eight times for the Saints since he moved to Franklin's Gardens from London Irish last summer.
The lengths of their respective deals have not been disclosed by the club.
"Both players have played important roles in their time at the club and we're confident they have more to give, both during the run in and for the coming years," director of rugby Jim Mallinder told Northampton's official website.
Northampton continue the defence of their league title on Saturday when they travel to rivals Bath.
