AS Albion's longest-serving player he signed a new four-year deal in September 2012.
Morrison joined Albion in a £1.5million deal from Premier League outfit Middlesbrough in August 2007.
His price was set to rise by a further £700,000 depending on appearances and Boro will also be due 15 per cent of any sell-on fee.
He further enhanced his reputation as a Barclays Premier League player during 2012/13, scoring five times in 35 league appearances from midfield. But in the 2013/14 season faced new competition in the shape of Stephane Sessegnon for the attacking midfield role.
Despite representing England at every level up to Under-20, Morrison pledged his international future to Scotland in the summer of 2007, qualifying through his grandparents, and made his full senior international debut in a 3-1 friendly defeat by the Czech Republic in May 2008.
His standing in the Scotland squad continues to grow and he captained them for the first time in their 1-0 World Cup qualifying win over Croatia in Zagreb, in June 2013.
He impressed during the 2011/12 campaign – winning the club's Goal of the Season award for his strike at Blackburn - in addition to a second-place finish in the Supporters' Player of the season award poll.
And that followed a 2010/11 season when he made 40 appearances for club and country, scoring his first goal for the national side in the 3-1 Carling Nations Cup win over Wales in the May.
The midfielder suffered a frustrating 2009/10 season as he had to wait until March before bringing to an end a ten-month lay-off with a niggling heel problem.
He squeezed in five starts and six substitute appearances in the league - and fired a spectacular 38th-minute opener in a 3-0 win over Leicester.
The midfielder was one of Albion's most consistent performers during the 2008/09 season and scored three times, including one in each of the Baggies' two derbies with Villa.
His form saw him finish as one of the runners-up for the club's official Player-of-the-Season award.
But he was forced to miss the final five games of the season due to a troublesome heel problem that required surgery in July 2009.
Morrison showed his versatility during his first season at The Hawthorns with a string of sparkling displays across the midfield.
And his six-goal tally included crucial last-gasp strikes in the 2-1 win over Blackpool and 4-3 victory over Colchester, both at The Hawthorns.
He made his Boro first-team debut at the tender age of 17 as a substitute in the FA Cup win over Notts County in January 2004.
The Darlington-born man also played a key role in Boro's FA Youth Cup triumph that year, scoring two crucial goals in the 3-0 final first leg win at Villa and terrorising their defence in the return match.
He stepped up to the first team again in September 2004, netting in Boro's 1-1 draw at Banik Ostrava in the UEFA Cup.
Morrison kept his place for the Premiership visit to Old Trafford three days later and made Stewart Downing's early goal as an injury-hit Boro side again drew 1-1.
He added to his collection of honours in May 2006 by bagging a UEFA Cup runners-up medal after being named in the starting line-up for the final in Eindhoven.
In total, Morrison made 98 appearances for the Teessiders, including 38 as a sub, netting eight goals.
