Bolton have completed the signings of Aston Villa defender Zat Knight and Hull City full-back Sam Ricketts on three-year deals.
Centre-back Knight, who has won two England caps, joined Villa in the summer of 2007 from Fulham in a £3.5million deal but struggled for first-team football.
Wales international Ricketts, who can play on the left or the right of a back four, started 27 of the Tigers' Premier League games in their debut season in the top flight.
Bolton boss Gary Megson is delighted to have sealed the deals after convincing both players to ignore other options and move to the Reebok Stadium.
Megson told the Trotters' official website: "We are really pleased that we could complete the deals. Both players had other offers to consider.
"I am sure that they will fit in to the squad and we are going to make sure that we help them with their new challenge.
"Zat has plenty of Premier League experience and has played at the highest level with England, while Sam personally had a successful debut Premier League campaign with Hull."
Knight and Ricketts are Bolton's third and fourth signings of the summer, with the club having brought in Sean Davis after his contract at Portsmouth expired and also Paul Robinson from West Brom.
